IMPROVEMENT IN CAPSTANS FOR DITCHING -PLOWS.

Specification forming part of Letters Patent No. 29,258, dated July 24, 1860.

Y To all whom it may concern:

Be it known that I, ELIAS FORBIS, of London, in the county of Madison and State of Ohio, have invented certain new and useful Improvements in Capstans for Ditching; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the annexed drawings and letters of reference marked thereon.

The nature of my invention consists in the employment and arrangement of such devices, the peculiarities of which will be hereinafter fully set forth.

To enable others skilled in the art to make and use my invention, I will now proceed to describe its construction and operation.

In the drawings, Figure 1 represents a perspective showing the machine complete and ready for operation. Figs. 2 and S'show the manner in which the front axle is hinged to the frame.

In Fig. 1, A represents the frame.

D is an upright frame, which is secured to frameA and located near its front end.

B is a capstan, which rests upon one of the cross-pieces of frame A, and extends up through and above the cross-piece of frame D, as fully shown in Fig. 1.

mis an iron axle, each end of which is turned downward at right angles, and then again bent at right angles, in order that wheels may be placed thereon.

O 0 represent two levers, which are secured to the top of axle m, between the frame A and the wheels upon which the hinder portion of the frame rests.' Said levers are then bent at an angle of about forty-five degrees in the direction of the front of the machine, their ends being turned back in the form of a hook, as fully shown in the drawings.

n represents the front axle, which is hinged to the front of frame A in such a manner that the axle can roll from under the frame.

G represents the tongue, which is secured to the front axle. Said tongue is provided with ajoint, as shown in Fig. 1.

It will be observed that when axle n is from under the frame A the tongue G will be in an elevated position. This joint, therefore, is to enable the front end of. the tongue to be lowered, in order that power may be applied to the tongue.

e is a slide for the purpose of slipping over the joint when the machine is in motion.

a: represents a brace or lever, which is secured on top of the tongue and pivoted to axle n, as may be seen in Figs. 2 and 3.

d is a cord, which passes through the hooks on levers O O, and round through staple or hook i on the tongue G.

The operation of my machine is as follows: A long rope being secured to the plow, the other end of said rope is attached to capstan B. Horse-power is then applied to a lever passing through the top of capstan B. As the plow is drawn forward by means of the rope pass.

when power is applied to the tongue it forces the axle under the frame. Said frame being thus thrown upon wheels is ready to be moved off at a distance from the plow again.

It will be seen that as the tongue is lowered the levers O G are pulled forward by means of the cord 01, attached to the tongue, thus elevating the hinder portion of the machine.

The object of this invention is to enable the grabs K K to be easily extracted from the earth when they have become embedded by reason of the great pressure to which they are subjected from the mole-plow.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The levers O G and cord at, or their equivalents, when both shall be operated in the manner and for the purposeherein substantially set forth and described.

2. Gapstan B, hinges a a, tongue Gr, slide 6, brace or lever 00,-in combination with levers O C and cord (1, the whole being arranged in the manner and for the purpose herein sub stantially set forth and described.

ELIAS FORBIS.
